Specification of Letters Patent.

Patented Apr. 3115, Lillie.

Original application led April 7, 1913, Serial No. 759,387. Divided and this application filed September 29, 1913. Serial No. 792,1L39.

To all 'whom t may concern.'

Be it known that I, ROBERT l. Soo'rr, a citizen of the United States, residing at Ohio, have invented certain new and useful Improvements in Green-Pea-Vine-Hulling Machines, of which the following is a specification, this application being a division of my cepending case,.Serial No. 759,387, filed April 7, 1913. Y

My invention relates to green pea vine hulling machines and tc an improvementl upon such machines as vshown in Letters Patent Nos. 499,397, June 13, 1893 to R. l). Scott, 957,449. May 10, 191() to RQ?. Scott; 957,443, May lo, 191,0 to n.' P. seca; @mail May l0, 1910 to T. Scott; 500,299, June 27, 1893 to Scott and Chisholm. These machines comprise an outer screen drinn provided with inward-projecting; lifting ribs, and an inner part with beaters, which latter when rotating are siaced inward 'from the innermost portions of' the liftingI ribs,

so that the pods are not torn apart by a threshing action, but burst open by impact. The object ci my invention is to improve upon all former machines in a respect that will increase the efiiciency of the machine and its capacity to hull and'separate peas. The invention consists in the construction oi the outer cylinder, especially in relation to the elevating ribs and screening surfaces.

ln the drawings,

Figure l shows a transverse section of the outer elevating cylinder and ribs ccnnecting the two end rings.

Fig. 2 shows a detailed perspective view of one elevating, rib. I

Fig. 5i shows a perspective ot the elevatrib and tivo adjacent sitting surfaces.

Pea vine hailing machines are in almost universal use for hulling green peas from the vines and as is well known consist oi a frame provided with travelers supporting an outer revolnble cylinder or druinwith ammlar ends. The ends of the drum are connected by elevating ribs. An inner drum or prism integral with a central shaft carries the beaters. rl`he feed ends of both drums and the lifting ribs and beaters are shown in'llig. l.

The six sides of the outer drum are covered by screens which may be of sheet metal or wire.l perforated rubber, llowever, having' been most used in the past.

y as the peas and vines roll over Perforated rubber l Fig. 1 isheldwin'the frames secured to the elev'ating'ribs 2.

The inner beater carrying drum 3 carries around and up to about the 1l ocloclz posi'- mowcd in bulli from the i'ieldvtion indicated by the numeral lla when' they are'dropped oit' into the path of the more rapidly revolving;` beatersl.

The beaters striking the vines throw them across to about the 2 ocloclr position indicated by the numeral 9i. rlfhe *foregoing operation has been common in pea vine hulling machines, but it will be seen that when the vines are struck Aand any of the peas liberated there has been but one chance ci discharging thehulled peas on the two oclocl; side of the. machine. That is, first,

it' the peas strike a perforation fairlyA and are thrown through the outer screening sur'- ace. Otherwise they `would strike the rub ber covering; between the l,holes and ydrop down upon the mass of vines and be imprisoned between the vines andthe upper surface of the lifting ril.k That peas are thus retained inside is in; icatcd by the fact that most all oi the hulledpe'as are iound directly under the seven goclock position showing that the principal siftingis done at that point.

in accordance with this invention the hulled peas are given a better chance to get to the outside at once, as they are struck and thrown across the top. rlhat is to say if the peas once get away from the vines l now give them less chance to get mixed up 4again. The rib does. not run ont against the frame 19 of the rubber covering as herctofore but only nt places or intervals .20 to support the .iframe li. l make a space between the lifting rib and the perforated screen, the rib being spaced or eut away at 2l so that if any hullcd peas are loose from the vine they will pass between the rib and siel 'themselves f los sifting surface ofthe screen below Whereas otherwise hulled peas would be held imprisoned at the outer edge of the lifting rib and the screening surface if no space Were 5 provided between the rib and the screen.

rllhe spaces are of slot-like character, eX- tending lengthwise of the ribs at their` outer edges, between the saine and the Wall of the drum. The slotted openings at the outer edges of the ribs also obviate the accumulation of dirt and debris Which may occur adjacent to the screen fabric when solid ribs are employed.

Claims:

l. ln a green pea Vine hulling machine a drum, a screening surface forming the Wall of the drum and a solid lifting rib constructed and arranged to leave a space for the peas to pass between the screening sur- 0 face and the rib and a rotating,l beater carrying member Within said drum.

2.. In a pea vine hulling machine, the combination of a shaft, a drum, a plurality of perforated outer screenscoveringl said drum, a plurality oi solid lifting ribs, said Aribs being so arranged with relation to said screens as to Bjrovide a passage between the ribs and 'the screens and a rotating beater carrying member Within said drum.

3. A green pea vine hulling machine comprising an inner beater carrying prism and` theouter drum provided With longitudinal lifting ribs and a perforated cover, said lifting ribs being substantially imperiorate,

-except at points adjacent to the cover Where they are open substantially as described.

fl. A green pea vine hulling machine, comprising an outer member consisting of a screen drum with lifting ribs, and an inner drum with beaters which rotate in a space inward of the innermost portions of the lifting ribs, the said outer member being provided with longitudinal openings eX- tending lengthwise of the drum and located at the outer edges of the lifting,` ribs.

5. In a green pea vine hulling machine, a rotary screen drum having lifting ribs spaced from the drum by longitudinal openings at the outer edges of the ribs and a rotating beater carryin,r member Within said drum.

(3. In a Kgreen pea vine hulling machine, the combination with an inner beater-bearing part and an outer sereen-carryingdrum, of lifting ribs on said screen drum formed with longitudinal slots in their outer edge portions adjacent to the screen carried "by the drum.

In testimony whereof, l have signed my name to this specification, inthe presence of two subscribing Witnesses! ROBERT P. SCTT.
